Looks like no ones posted here in a while, but the version I learned as a kid for the flea song went (and I'm just spelling as things were pronounced)

flea
flea fly
flea fly flo
cumula cumula cumula vista
oohhhh no, not la vista

eenie meenie mussolini
ooo ah ah,
ah ma-lini
ocha cocha cumoracha
oo ah ah
ish killy oaten boaten
o boe ba ditn dot

I remember learning it in fourth grade, and I remember the teacher teaching it to us because she said it would help us remember something. But I don't remember what, LOL.
